Abstract Objectives and Participants: Changes in body weight, composition, and size were examined in college freshmen at the beginning (initial, n = 240) and end of fall semester 2007 (n = 214) and the end of spring semester 2008 (n = 205). Methods: Height, weight, body composition, and waist and hip measurements were assessed. Results: Mean weight, body mass index (BMI), absolute and percent body fat all increased significantly over fall semester and the academic year. About 31% of freshmen lost ≥5 lbs. Mean academic year weight gain was 2.6 lbs (entire group) and 6.0 lbs (weight gainers); body fat increased by 4.4 lbs in the weight gainers. A significant correlation (r = .509) was found between weight change and waist circumference change, but not between weight change and waist to hip ratio change. Conclusions: Freshmen weight gain is associated with increases in body fat and waist circumference, which may be troublesome should the trend continue throughout college. 相似文献

In this article, the author addresses areas of complexity within evidence-based social work practice that she has encountered in her work with clients. The author offers an in-depth case study from her practice that involves the assessment and treatment of a client with a complicated diagnostic presentation. Clinical choices are discussed using a biopsychosocial framework that highlights the importance of attending to the client's specific needs as the author select interventions based on the best available research. 相似文献

The problem of estimating the width of a symmetric uniform distribution on the line together with the error variance, when data are measured with normal additive error, is considered. The main purpose is to analyse the maximum-likelihood (ML) estimator and to compare it with the moment-method estimator. It is shown that this two-parameter model is regular so that the ML estimator is asymptotically efficient. Necessary and sufficient conditions are given for the existence of the ML estimator. As numerical problems are known to frequently occur while computing the ML estimator in this model, useful suggestions for computing the ML estimator are also given. 相似文献

This study investigates the joint effect of corporate ownership and board of directors' diversity configurations on the success of strategic merger and acquisition (M&A) decisions. Board diversity is defined as the extent to which its demographic diversity as measured by the culture, nationality, gender and experience of its directors complements its statutory diversity. A theoretical framework linking ownership, board diversity and M&A strategic decision making is proposed and tested. Based on a sample of 289 M&A decisions undertaken by Canadian firms over the period 2000–2007, demographic diversity is found to have a clear and non‐linear effect on M&A performance while statutory diversity is of limited influence. Ownership is found to influence the effect of diversity, making the relation finer and more precise. This has practical implications. First, statutory diversity is not sufficient for well‐performing boards. Also, ownership is an important factor. The most advocated board diversity aimed at insuring the board's independence is not valid across all ownership configurations. From a public policy perspective, results provide support for the principles‐based approach in governance. Governance regimes should encourage the search for a balance between board diversity and the need for cohesion that best serves the firm's purpose and obligations. 相似文献

Although of considerable practical importance, the separate impact of individual and collective reputation on firm performance (e.g. product prices) has not yet been convincingly demonstrated. We use a sample of some 70 different wineries offering more than 1,300 different Riesling wines from the Mosel valley to isolate the returns to individual reputation (measured by expert ratings in a highly respected wine guide) from the returns to collective reputation (measured by membership in two different professional associations where members are assumed to monitor each other very closely). We find that both effects are statistically significant and economically relevant with the latter being more important in quantitative terms than the former. 相似文献

优化资源配置 ,不仅需要完备的市场体系和自由企业制度 ,还需要一套完备的宏观调控政策体系。区分与确认这个政策体系中的长期政策与短期政策至为重要 ,人们不能指望在短期内实现长期政策的目标 ,也不能指望短期政策发挥无限期的效力。稳定长期政策 ,适时调整短期政策 ,宏观调控才能收到良好效果。 相似文献

This paper explores the earnings gap between West Indians and African Americans that cannot be explained by observable characteristics and is often interpreted as a measure of discrimination or unobservable cultural endowments. The earnings gap advantage has lead to many perceptions and some unsubstantiated implications as to the reasons why West Indians perform better than African Americans in the labor market. This is an attempt to sort out the implications and to put the West Indian/African American earnings difference in prospective. 相似文献

Open Dialogue is a collaborative systemic approach to working with families in crisis. A core feature is the creation of dialogue through the elicitation of a multiplicity of voices. Using conversation analysis, we studied 14 hr of Open Dialogue sessions. We found that therapists recurrently produced utterances containing “I’m wondering.” These utterances topicalized particular issues and invited stance positions from other participants while also allowing the therapist to mitigate their deontic authority and present potentially disaligning stances. Therapists thus exercised authority in eliciting stances, but provided recipients with multiple avenues for responding. These findings illustrate that therapist authority is not necessarily antithetical to dialogue and, in well‐crafted forms, may even be necessary for the creation of polyphony through the elicitation of multiple stances. 相似文献
